Kier and BAM Nuttall, with their specialist geotechnical division BAM Ritchies, are in a fully integrated joint venture to deliver the OH2001 Earthworks, site preparation and infrastructure for the new nuclear power station at Hinkley Point C (HPC).
The power station will incorporate two 1650 Megawatt European Pressurised nuclear reactors (EPR), together capable of generating electricity for approximately 5 million homes and a range of shared facilities.
Situated over a site 2.1km x 2.2km wide (the equivalent to 245 football pitches!) adjacent to the Severn Estuary, HPC is approximately five miles from Bridgwater and the M5. At the peak of construction, it is anticipated the Kier BAM Joint Venture will have a workforce of c1,500 people.
- Excavation of areas including the main reactor dig, and the processing and placement of engineered and landscaped fills. Excavation of approximately 5.6million m³ of rock and overburden and the treatment and reuse of the material.
- Site preparation and restoration – remediation, stockpile management and restoration.
- Roads and networks approximately 15km of construction phase roads, a north bus and south delivery plaza, ducts, drainage (40,000m) a water main and street lighting.
- Structures, including a 760 metre long sea wall, a 400 metre piled wall, multiple retaining walls and temporary and permanent bridges.
A deep dig area which involves the construction of the foundations for the nuclear power station. The deep dig entails deep excavation which will sink to approximately 31 metres at the deepest level. Soil nailing (c100,000m) and spray concreting (38,000m³) operations will be undertaken during the construction of the excavation faces. Placement of rock protection blinding concrete (foundations to the nuclear structure) using nuclear grade concrete delivered to nuclear quality standards.
Installation of earthing system under nuclear buildings to nuclear standards. Facilitating the deep dig / excavation works will be the installation and operation of a de-watering system which comprises multiple pumped de-watering wells. At peak, the deep dig section will be placing around 2,000m³ per week.
